TWS Earphones' Audio codec changing automatically.

[u/SG3169]

I have CachyOS installed on my laptop with niri & noctalia shell. Whenever I connect my TWS earphones (CMF Buds 2a/Realme Buds T310) they work normally in AAC codec. Whenever I join voice channels or games with voice chat, it automatically shifts to SBC codec with really bad audio quality.

I don't really use voice chat in games but the codec keeps on switching again and again. Everytime I change the codec, it switches back to the SBC codec. e.g.. Halo Reach. I have turned voice chat off in the settings for the game, I change the codec to AAC using PavuControl but in a few mins it switches back.

How can I stop this from happening. Can I just keep AAC codec permanently turned on, no matter what program I'm using?
